Great Sky is a venture-backed startup developing AI hardware to enable intelligence at the boundaries of physics. By using light for communication at the single-photon level, we achieve physical limits of speed and energy efficiency. By computing with superconducting electronics, we leverage devices that have the highest speed and lowest power consumption of any known circuit. By co-locating processing and memory we dramatically reduce data movement. While current approaches struggle for a few-percent improvement in price and performance, Great Sky's reinvention of AI hardware from the physics layer delivers multiple orders of magnitude improvement that will enable AI to realize its potential.
